2021 S2S motor blew up!

[PMK]

Dealer left a message today. Said carbon build up on valves was causing no compression. I find that hard to believe. All stock motor. Always 91 octane ethanal free gas.

As we tend to say here, run fast and far from that dealership.
Did I ever mention the lack of talent in technical trades...

So if it truly were carbon buildup, holding valves open, you must have done one very long distance last ride if it went from good to bad, as if something broke.

One problem when techs work flat rate, troubleshooting is tough for letting them eat.

The last ride I did was a long distance highway ride, but if this really happened, then more people would have the same issue.

"carbon build-up " :roflblack::roflblack::roflblack: ....if that's true ( NOT ) then it's an easy fix and you have the bike next week .... good luck .... Mike :thumbup:

 

[Joel The Biker]

They said they cleaned the carbon. How? Removed the head? I want more answers. Mike, how is it an easy fix? The bike would not start, so you cant seafoam it. I dont believe in seafoam anyway. No fuel additive is going to instantly clean valves. Carbon build up in less than 7000 miles? No way. This spyder will be sold. I am not going to be left stranded somewhere.

I may be wrong ,but at 7000 miles with that much build up to not run, I’d think oil would be running out exhaust by then. Did they scope it? That’s the only way without popping the top. No way its carbon! Sure, maybe a little, but not that much. My 1200 BRP sled has 15000 miles and yes I seafoam over summer and run hot first tank but there’s little carbon on that and sleds take a beating with temps and RPMS. If it was 500 miles sure I can see for some reason it not seating if it was totally abused and over reved the entire time but not 7000 no way. Something came loose or slipped. What do the plugs look like? Id start backwards and work in first.

.

BRP need to take this lemon back and give you a new one!!!!

 

[UtahPete]

There's just simply not enough information to draw any conclusions at this point.

 

[Freddy]

Whatever. The old relyability Spyder bytes again.

I meant long distance like 100 hours operating time at the same throttle setting.
Offer up a gram of credit to me that I can see through your dealers antics and lack of skill to correctly diagnose a problem. Your first hunch of not letting touch it was valid. The manager is likely a salesman and sold you on his best bag of lies. The tech saying it is carbon build up, seriously, are we dealing a 1935 Ford here.

I await your next report of how they repaired it, I need the laugh, and honestly believe, nothing has been repaired if they got it running. The tech simply got lucky for an instant and will go down in flames ultimately.

Why techs think everyone else is dumb and not mechanically inclined, is numbing. Having read what you work on, and knowing what I work on, and Spyders are not our day job, I find the Spyder pretty simple and typical mechanically, and even electronically. As owners, just as we are car owners, the manufacturer refuses to offer the electronic programing to accomplish updates or reflashes to the public. This is where the 1935 Ford is superior.

Spoke with another spyder mechanic who said he had one that had the same problem. Customer dropped it off for maintenance.
Two days later it wouldnt start. Carbon was causing the valves to stick open. Supposedly BRP remapped the newer bikes to prevent it from happening. Seems to me this would be a common topic here. Why did mine carbon up? Month ago i put on an Akrapovic muffler. That shouldnt do it. Other than that, its all stock and ridden the same as my 2014 with the same motor. I am at a loss. The for sale sign will go on it this weekend.

Why did mine carbon up? I used to have a bypass pipe on it. But so does everyone else. Month ago, put cat back on and switched to Akrapovic muffler. That shouldnt do it.

As far as I know, you are our first notification of this happening. Others will let me know if I am in error. :thumbup:

I'm pretty sure you are right. My B.S. meter has been pegged for some time now...

Priced as a lemon, with full disclosure, I hope.

Sounds like the mapping is off to cause that. Now what would happen if you went after market and remapped yourself. Could be a sensor throwing off something causing your issue?

If that was the only problem was carbon fouling?

 

[pegasus1300]

So are you saying you have it back and it starts and runs and you can drive it but you do not trust it?

As I understand it, that was the dealer owner's best guess. Based on what? Nothing.

My 2019 F3L shredded the oil pump gears at 5000 miles, but was able to limp home. Due to probable further damage, BRP replace the engine under warranty. Took awhile to get it back.
